The constants C,, C,.,..C, can be calculated from (16%, resp. 
(16%. In this discussion we met with determinants analogous to 
those obtained in determining the C’s for the case I. 
Representing graphically the currents I (7), or II (157) and 15%, 
we obtain analogous curves. We confine ourselves to an example 
of the second case. 
The curves in fig. 1, 2 and 3 represent the changes with the 
time of the current in every circuit of a series of 10 circuits which 
are magnetically coupled. 
We assumed an electromotive force in the first circuit to be 
stopped suddenly at the time zero. The magnetic energy of the 
current in the first circuit excites an induction current in all the 
other circuits. The circuits have been numerated 1, 2, 3... 10.
